Infrared human image is not enough contrasted, and gray overlap between background and human targets. A PCNN improved with Fisher criterion image method is proposed for these problems. The fisher criterion-based segmentation method achieve good segmentation in low image contrast. PCNN segmentation method is suitable for image with gray overlap between object and background. Combined these two method...
A ripe tomato recognition and localization system for tomato harvesting robotic systems in greenhouse is developed. The ripe tomato is segmented by K-means clustering using the L*a*b* color space. To extract a single ripe tomato, mathematical morphology is used to denoise and handle the situations of tomato overlapping and sheltering. Tomato's shape features are combined with the color features to...
A robotic system for harvesting tomatoes in greenhouses is designed. Effective recognition of ripen tomatoes from complex background is the key technology of the harvesting robotic system. In this work, the color feature of ripen tomatoes is employed. The ripen tomato is segmented by K-means clustering using the L*a*b* color space. To extract a single integrity ripen tomato, mathematical morphology...
